Abstract:
The purposes of this research were 1) to study the definition elements of extra
role behaviors and thefactors influencing teacher's extra role behaviors 2) to investigate
the validity of measurement models of self-efficacy in extra role behaviors, workplace
friendship, personal initiative, motivation in extra role behaviors and teacher's extra
role behaviors with empirical study 3) to investigate the validity of causal relationship
model of teacher's extra role behaviors with empirical study 4) to study the effect of
the development teacher's extra role behaviors program. The research was divided
to 4 stages following the purposes.
Phase 1 was a qualitative research. The samples of this study were 12 elementary
school teachers in the area of Mueang District in Eastern Thailand.The data were
collected by interview and were analyzed by content analysis.Results indicated that :
the definitions of extra role behaviors mean "willingness to help the students, co-workers,
schools and communitiesis beneficial. It is not obligation. Moreover, it excludes

Phase 2 was a quantitative research. The samples consisted of 206 elementary
school teachers in the area of Mueang District in Eastern Thailand including Sakaeo,
Prachinburi, Chachoengsao and Trat. Confirmatory Factor Analysis (CFA) was used to
analyze data. Results indicated that all measurement models were consistent with
empirical data.
Phase 3 was a quantitative research. The samples consisted of 503 elementary
school teachers in the area of Mueang District in Eastern Thailand including
Chanthaburi, Chonburi, and Rayong. In this study, questionnaires were used to collect
data about five variables as follows: self-efficacy in extra role behaviors, workplace
friendship, personal initiative, motivation in extra role behaviors and extra role
behaviors. Structural equation modeling (SEM) was used to analyze data. Results
indicated that the structural model was consistent with empirical data. 56% of the
variance in associated with extra role behaviors was explained by four predictors.
Specifically, workplace friendship had the strongest direct effect on extra role
behaviors.
Phase 4 was a quantitative research. The samples consisted of 12 elementary
school teachers in the area of Mueang District in Eastern Thailand. In this study,
instruments were questionnaires and the development of teacher's extra role
behaviors program. Friedman TestandWilcoxon Signed-Rank Test were used to
analyzed data. Results indicated that there was difference in teachers extra role
behaviors between before training, after training and follow up period at a
statistically significant level of .01 andafter trainingwas higher thanbefore training,
follow up period was higher thanbefore trainingand follow up period was higher
thanafter training.
